METHQD OF MAKING:y TOILET SEATS.

Application filed 'March 20, 1928. Serial No. 263,143.

l tion is fully concealed.

Seats of this general character are wellknown and numerous methods have heretofore been employed in their construction. The primary consideration, however, in the manufacture of this type of seat is to so assemble the sections of which the seat is composed as to make absolutely closed joints which will not open even after long periods of use. It has been suggested heretofore to assemble seat sections by the application of pressure to the exterior edges of the outer sections, in order to .force tie members into the respective sections. Hydraulic vpresses are generally employed for this purpose and considerable pressure'is used. It is found in practice, however, that when pressure is applied, as stated, the natural resiliency of the wood acts as a cushion. In effect it tends to take up the pressure and spring back when the pressure is relieved so that it is very difficult to get the joints absolutely tight initially and to maintain them `tight thereafter.

With the foregoing considerations in mind I have conceived the present method of this invention which, instead of utilizing pressure directed upon the parts remote from the anchoring means, tension is utilized to draw such sections together. This tension, moreover, is applied to the respective sections in such manner and in such localities as to eliminate the disadvantages to which I have referred and to insure permanently tight joints. j

Thus, 1n practicing the present invention, I apply tension to the respective sections adjacent to the edges which are to be brought into abuttin relation and utilize this tension, as app ied to the respective sections, to force tie members simultaneously into the respective sections. In other words, the sections are drawn together in contradistinction to being forced together by externally applied pressure. In one of the practical modes of practicing the invention, in connection, for example, with a two-piece seat the edges of the respective sections whichl are to be broughtinto abutting relation are squared true so asfto make a proper joint to receive tension members.

when brought together. The sections are then provided with lined holes adapted to receive tie members. These tie members are in the form of double-ended screws, the central portion of each of which is left unthreaded, while the opposite ends have right and left hand threads or convolutions. The opposite ends of the sections are notched out contiguous to the tted edges and from the bases of these notches lined holes are bored The holes bored for these latter members are slightly smaller than said members while theholes bored for the tie members are slightly smaller than diameters' of said members,

the-purpose being to permit introduction of the respective members without splitting the vwood and yet permit the threads to get a good-grip.

By the employment of the tension members-the sections may be drawn together for the purpose of forcing the tie members simultaneously into the holes of both Sections in orderto aect a tie joint and anchor the parts together.

Features of the invention other than those specified will be apparent from the hereini 'in carrying out the method.

Figure 8 shows one'of the tie members.

Figure 9 illustrates the method of this invention as practiced in the making of a four-piece seat.

In making'a two-piece seat, in accordance with the present invention, I start wlth two pieces of wood which are irst cut, as shown in Figure 1, to form two sections, l' and 2, which are identical witlrone another. 'Ihe edges', 3 and 4, of these sections are the lonted edges whichl are adapted to be rought together to form theV joint. Adjacent to` these edges, at opposite ends of each section, notches are. cut out, as shown at .5,

- 7, Sand 9, are bored so that the holes, 6,'and

7, will be in alinement and the holes, 8 and retracted slightly before introduction of the tension members, the tension members will operate easily at the start of the nextv opera- 9, will Abe similarly positioned. Holes, 10,` A tion which consists in rotating thetension 11, 12 and 13 are also-bored in respective sections to project inwardly from the edges, as shown, and in such position that 'the holes, 10 and 11, will be in alinement and that the holes 12 and 13, will be similarly disposed. The holes, 10, 11, 12 and 13 are intended for the reception of tie members, one of which is shown in detail in Figure 8. Each tie member is provided with a central portion, 14, while beyond the opposite ends of the portion, 14 the tie member is provided with right and left handfthreads, 15 and 16, respectivel. I wish to call particular attention to t e fact that the threads, 15 land 16, areof an' unusually long pitch e. triple thread, so as to screw into wood vwi along lead and with expedition.

The holes, 6, 7, 8, and 9 are adapted to cooperate with tension members, one of which is shown in Figure 7, each tension member has a'central polygonal portion 17, and opposite end portions` 18 and 19, are provided with right and left hand threads, res ctively. The threads of the parts, 18 an 19, are similar to those employed on lav-screws and their pitch is materially less t an the threads of the tie members. The purpose of this arrangement is to provide for the application of relatively great power through operation of the tension members in orderto cause the tie members to enterl the holes, 10-'13. `The lon lead of the tie members permits them to Ee anchored easily while the short lead of the tension members allows of the application of relatively great power.

In assembling \the parts they are first brought into the position shown inFigure 1 with the opposite ends of the tie members entered into the holes, 10-13. The tie members are then rotated, either manually or by the use of any appropriate machine to screw them into the respective sections. Ivlliis operationwill cause sections to be drawn together and is continued until they are in about the relation,\shown in Figure 2. The tie members are thereupon backed oil or unscrewedl slightly to approximate the position of the parts, shown in Figure 3, and

the tension members are then brought into the positions shownA in this figure. From this point on the tie members are not directly operatedupon but in contra-distinction the tension members are operated by suitable machinery `:or manually to draw the sections together. A s the sections are drawn together the spiral or threaded portions of the-tie members cut threads in the holes, 10- 13, and are rotated to screw into the res ec-l tive sections by virtue of the tension to which said sections are subjected. Inasmuch as .the tie members have been members to draw the seat sections together so that by the time the tie members have to start again to cut their lown thread the tension members have cut sufficiently into the sections so as not to pull out. By proceeding with this operation the sections are drawn tivhtly together, as shown in Figure 4, therea ter the end portions ofthe respective sections are ,cut away, as shown by the dotted lines, 20, leaving' the finished blank, shown in Figure 5. T is blank is then acted upon by suitable woodworking machinery to shape it into the finished form, shown in Figure 6.

In Figure 9, I have illustrated the manner in which the methol of this invention is utilized in the method of a four-piece seat. Inthis figure the sections, 1A and 2^, correspond to the sections, land 2, but intermediate sections, 21 and 22, are added. These intermediate sections are bored to provide lholes for the tie members but these holes are sufficiently large to permit such tie members to readily slip therethrough. The parts are assembled in the same manner as previously` described although the tie members, shown in Figure 9, have a longer, Unthreaded, central section corresponding to the section, 14, and shorter threaded end sections so that suitable-tools may be applied to these tie members in order to carry out the method as 100 hereinbefore defined.

It will, of course, be understood that the joints-produced, as stated, may be doweled,

tongued and grooved, or otherwise suitably formed in order to produce a positive lock atthe joint so that there may be no displacement of the sections relative to one another in a direction perpendicular'to the faceliof the seat. As this practice is, however, wellknown in the art I have" not considered it necessary to illustrate these adjuncts.

lIt will further be understood tliatfthel parts cut away from the ends of the respective sections, as along the lines 20,*are separated from the tension members in order to permit of further use of said members' in connection with other seats. 'ff

I wish to call particularattention to the fact that the tension which serves to draw the sections together is applied from the edges which are to be joine It is a cbm- `mon practice to use fairly straight-grained wood in the manufacture of articles of the character under consideration and it, therefore, follows that the tension devices `act through substantially the same grain as receive the tie members. There is, therefore, little tendency of compression onl this grain and the power is localized in such manner as to produce the most efficient results.

I have not shown or described any particular mechanism, wrenches, or the like, for manipulating either the tie members or the tension members.. lIn practice, these may be operated upon either manually by the employment of wrenches or other implements,

`or they may be operated by any suitable power mechanism or machinery.

The parts are placed under no such compression as would cause them to expand in a manner to open the joints and experience has shown that the joints will remain tight indefinitely,

vThe foregoing detailed description sets fort-h the invention in its preferred practical application but the'invention is to be understood to be fully commensurate with the appended claims. v

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. The hereindescribed method of making a toilet seat which consists in bringing the sections of the seat into spaced-apart juxtaposition with right and left hand threaded tie membcrsprojected into alined holes in the respective sections, and thereafter draw- `ing said sections together by applying tension between them for the purpose of fully entering the tie members into the holes of the respective Sections and bringing the contiguous edges of such sections into abutting relation.

2. The herein described method of making a toilet seat which consists in bringing the sections of the seat into spaced-apart juxtaposition with right and left hand threaded tie members projected into alined holes in the respective sections, and thereafter applying tension between the contiguous edges of said sections to draw said sections toward one another for the purpose `of forcing the tie members to simultaneously rotate and enter said sections until the contiguous edges of the sections are in tight, abutting relation.

3. The herein described method of making a toilet seat which consists in bringing the sections of theseat into spaced-apart juxtaposition with right and left hand threaded tie members projected into alined holes in the respective sections, thereafter bringing additional right and left hand screw members into holes in the contiguous edges of said sections and through tightening said additional screw members to draw the sections together whereby the tie members are caused `to rotate and simultaneously enter the respective sections until the contiguous edges of said sections are in tight and abutting relation.

4. The herein described method of making a toilet seat which consists in bringing the sections of the seat into spaced-apart juxtaposed relation With tie members, having long pitch, right and left screw threads on their opposite ends, partially projecting into alined holes in respective sections through causing right and left hand tension screws, of less pitch, to .be screwed simultaneously into both sections for the purpose of drawing suc-hv set-tions together with greater power than resistance oered by the tie members whereby the sections are caused to move toward one another and screw the tie members into the respective sections until the contiguous edges of said sections are in abutting relation.

5. The herein described method of making a toilet seat which consists in bringing the 'sections of the seat into spaced-apart juxtaposed relation with tie members, having long pitch, right and left screw threads on their opposite ends, partially projectin into alined holes in respective sections t rough causing right and left hand tension screws, of less pitch, to be screwed simultaneously into both sections for the purpose of drawing such sections together with greater power than resistance offered by the tie members whereby the sections are caused to move toward one another and screw the tie members into the respective sections until the conti uousedges of said sections are inabutting fellation, thereafter removing the portions of the sections with which the tension members co-operate and thereafter shaping the resulting blank into the form of a finished seat.4

In testimony whereof I have signed the -foregoing specification.
